PUZZLE.

SPECIFICATION forming part of Letters Patent No. 553,648, dated January 28, 1896.v

Application filed May 31,1895. Serial No. 551,205. (No model.)

To @ZZ whom it may concern.'

.Be it known that I, CHRISTIAN II. T. HA- GELsTEIN, acitizen of the United States, residing in Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in Puzzles, of which the following, taken in connection with the accompanying drawings, is a specifcation.

My invention relates to a mechanical puzzle of novel construction and arrangement, and the object of the invention is to produce a mechanical puzzle which will be attractive and will require the exercise of some ingenuity to work out the required result. I accomplish this obj ect by the device illustrated in the accompanying drawings, in which- Figure 1 is a perspective view of the puzzle with the two halves in position to remove the igure. Fig. 2 is a similar view showing the halves in position to retain the figure. Fig. 3 is an illustration of the figure forming a part of the puzzle. Fig. 4L shows the shot or ball which locks the two halves. Fig. 5 is a perspective view of the two halves, showing the internal arrangement. Fig. 6 is a sectional view of the two halves placed together, and is taken on the line @c Fig. 5. Fig. 7 is a sectional view of the two halves placed together, and is taken on the lines g/ -y and .e s, looking in the direction of the arrows, Fig. 5.

Referring to the drawings, 1 2 are the two halves of the device, which consist of circular disks of metal or other suit-able' material fastened together so as to turn freely on their common centers, and each provided with concentric rings and grooves on one of its surfaces, as shown in Fig. 5. The outside rings 3 4 are not so high as the other rings, with the result that when the two halves are placed together a space 23 is left between their edges. The part to be removed consists of a pin 25 provided at one end with a head 2G and at the other end with some attractive figure-as, `for instance, a brownie7 The pin 25 is small enough to move freely in the slot 23 between the disks, while the head is retained in the groove 9 10. At one point in each of the rings 3 et the wall is cut away so as to form, when the two are brought together, the opening 21 through which the head 2U of the pin will pass, thus allowing the figure to be removed.

In each groove 11 12 are placed stops 2O 19 which are higher than the rings 5 G, and which project respectively into the grooves 12 and 11, so as to come in contact with each other when the disks are turned, and thus limit the movement of the two disks. Each stop is so placed in relation to the opening 2l that when the right-hand disk is turned in the direction indicated by the arrow in Fig. 2 the stops will hit each other when the two parts of the opening are about -in the position shown in this figure; but when the'disk is turned in the opposite direction the stops will hit each other when the opening is complete, as shown in Fig. 1, allowing the pin-head to be removed.

In the groove 11 12 and between the stops is placed a ball or shot 22. This shot being normally between the stops preventsthe completion of the opening 21 when the disk is turned in a direction opposite to that indicated in Fig. 2.

The rings 7 8 have respectively the openings 17 1S, and when these two openings coincide with each other, the disks being vin a vertical position and the openings at the top, the shot will pass from the groove 1l 12 to the groove 13 14, as shown in Fig. 7, thus allowing the disks to be turned to bring the opening in the position shown in Fig. 1, and allow the figure to be removed.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

A mechanical puzzle consisting of two disks pivotally connected at their common centers and turning on said pivot, each disk being provided on its inner surface with a plurality of concentric grooves Yand rings, the outer ring being less in height than the other rings and having a radial slot therein (as at 21); two stops 19, 20- inthe grooves 12, 11; a shot or ball 22- between said stops and freely moving in said grooves and adapted to drop through the openings 17, 18 into the groove 13, li when said openings coincide with each other, (the disks being in a Vertical position and the Openings at the top g) the removable pin 25 provided with a head #26- at one end and a suitable figure at the other end, all substantially as set forth and for the purposes specified.

In testimony whereof I have heren-nto subscribed my name this 20th day of May, A. D. 1895.
